-Here is how to setup the Raspberry Pi to support normal OpenGL (with acceleration) and be able to compile the Proton SDK examples. ​ ​It'​s actually also possible to set things up for GLES, but this is probably easier these days.  ​(tested with Raspbian "​Jessie"​ on 6/18/2016)+Here is how to setup the Raspberry Pi to support normal OpenGL ​or GLES (both with acceleration) and be able to compile the Proton SDK examples. ​  ​(tested with Raspbian "​Jessie"​ on 6/18/2016) 
 + 
 +From my tests I got it working two ways: 
 + 
 +1.  Set it up using the OpenGL experimental driver. ​ Result: Proton examples only work in X11 in windows mode.  Fullscreen (using the SDL2 harness) didn't work.  [[proton:​raspi_opengl_setup|Directions to setup]] 
 + 
 +2.  Set it up using GL ES, won't work in X11, works full screen by starting from console. ​ This is more useful for me as it's more pedal to the metal and easier to get 60 fps, no x overhead. ​ With this method we're setting up our own EGL context manually, but still using the SDL2 harness for other things

-You'll have to the copy the RTBareBones/​bin/​interface dir to /​RTBareBones/​linux as that has font/graphics needed.+The last step of the build copies ​the rtbarebones binary ​to /​RTBareBones/​bin (as that's where the media is), so go to that dir and run "./rtbarebones"​ and it should work.
  
-Running "./​rtbarebones"​ from the RTBareBones/linux dir should ​now work +RTSimpleApp is much the same, although you'll need SDL2's mixer as well ​Unlike with the base SDL2, we can just grab a pre-compiled one like this: 
 +<​code>​ 
 +sudo apt-get libsdl2-mixer-dev 
 +</code> 
 +And that should ​compile ok. We don't have a mouse or anything but I can see it's running at 60 fps...
  
-That should be enough to get you going.
